Waves, Light, and Sound

Grade 4 Science Worksheet - Building Confidence

NameDate

Circle the answer.

  1. Wave A has crests 2 cm apart. Wave B has crests 6 cm apart. Which is true?

    • Wave B has the longer wavelength
    • both have the same wavelength
    • Wave A has the longer wavelength

  2. Water waves in a tray have a small amplitude. A student makes the waves taller. What else is true?

    • the waves now carry less energy
    • the crests are now farther apart
    • the waves now carry more energy

  3. What is the lowest point of a wave called?

    • the crest
    • the amplitude
    • the trough

  4. Why can't you see your book in a completely dark room?

    • your eyes stop working at night
    • no light bounces off it into your eyes
    • the book disappears in the dark

  5. Which object reflects the most light?

    • a black cloth
    • a piece of dark felt
    • a shiny mirror

About this worksheet

Waves, light, and sound models help students explain patterns they can observe but not always see directly asks fourth graders to connect observations with an explanation, model, or design decision instead of choosing a fact from memory. Students may confuse a wave property with a material property, or think eyes send out light instead of receiving reflected light from objects. This worksheet uses short investigations and evidence-based situations so students must read what happened, decide which science idea is being tested, and choose the answer that fits the title.

Students interpret amplitude and wavelength, model how reflected light lets us see, and compare sound or light patterns used to transfer information. Support versions use familiar objects and direct wording. Standard and challenge versions add closer distractors, fair-test language, and multi-step evidence. Ask your child to point to the measurement, diagram, map, or observation before answering. If the choice does not explain the evidence in the prompt, it is probably a distractor. That habit keeps science reasoning tied to data rather than guesswork.

What your child will learn

  • Model wave patterns
  • Relate wave properties to observations
  • Explain how reflected light enters the eye
  • Use patterns to transfer information

NGSS standard: 4-PS4-1

Worked example

A drum sound with larger amplitude is louder, while seeing the drum requires light reflecting from it into the eye.

Common mistake

Saying the eye shines light onto objects instead of receiving reflected light.

Helpful hint

Match the model to the observation: wave pattern, reflected light, or information signal.
